What is chain of infection quizlet?

STUDY. CHAIN OF INFECTION. Transmission occurs when the agent leaves its reservoir or host through a portal of exit, is conveyed by some mode of transmission, and enters through an appropriate portal of entry to infect a susceptible host.

AHE: The Chain of Infection

What are the 3 steps in the chain of infection?

What is the chain of infection definition?

The means by which an organism transfers from one carrier to another by either direct transmission (direct contact between infectious host and susceptible host) or indirect transmission (which involves an intermediate carrier like an environmental surface or piece of medical equipment).

How many links are in the chain of infection?

Certain conditions must be met in order for a microbe or infectious disease to be spread from person to person. This process, called the chain of infection, can only occur when all six links in the chain are intact. By breaking this chain at any of the links, the spread of infection is stopped.

Which of the following is the first link in the chain of infection quizlet?

First link in the chain of infection - the person who carries the pathogen.

Which factors are included in the chain of infection quizlet?

What are the stages of infection?

The five periods of disease (sometimes referred to as stages or phases) include the incubation, prodromal, illness, decline, and convalescence periods (Figure 2). The incubation period occurs in an acute disease after the initial entry of the pathogen into the host (patient).

What is the chain of 5 F's that can cause infection?

The common factors in the fecal-oral route can be summarized as five Fs: fingers, flies, fields, fluids, and food. Diseases caused by fecal-oral transmission include typhoid, cholera, polio, hepatitis and many other infections, especially ones that cause diarrhea.

What are the 5 basic modes of transmission of infection?

What are the 5 modes of transmission quizlet?

Which of the following is the first chain in the chain of infection?

1. The pathogen. The first link in the chain of infection is the infectious agent or pathogen which can take the form of: Viruses – such as Influenza A, shingles and Hepatitis.

What is the best way to break the chain of infection quizlet?

One of the most effective ways to break the chain of infection is hand washing. Under Universal Precautions blood and certain body fluids from all individuals are considered potentially hazardous. Any body fluids with visible blood should be considered potentially hazardous and all appropriate PPE should be worn.

How is the chain of infection broken?

The chain of airborne-based infections can be broken by following these measures: Practice proper patient placement in an airborne infection isolation room. Limit healthcare staff from entering the room, especially those vulnerable to infection. Use appropriate PPE such as an N95 or equivalent respirator.

Which of the following are means of breaking the chain of infection quizlet?

Way to break chain at thetransmission. Prevent contact by proper hand washing, disinfection/sterilization techniques, isolation of infected patients, and not working when contagious.

What are the 4 routes of transmission?

What are the four main routes for infection to enter the body?

Microorganisms capable of causing disease—or pathogens—usually enter our bodies through the eyes, mouth, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread, or be transmitted, by several routes.

What is the chain of infection Covid 19?

The virus enters the body by coming into contact with the mucusa of the eyes ,nose and mouth. Either by breathing in the droplets from an infected person or by transferring the virus by touching a contaminated object and then touching the eyes, nose and mouth.

How do you remember the chain of infection?

What is the chain of infection a model of?

This model explains the spread of a communicable disease from one host (or person) to another. The basic idea represented in the chain of infection is that individuals can break the chain (reduce the risk) at any point; thus the spread of the disease can be stopped.

What is the portal of exit in the chain of infection?

The Portal of Exit refers to any route that the pathogen can leave the reservoir. This depends entirely on the characteristics of the reservoir. In humans, the main portals of exit include: Alimentary: vomiting, diarrhea, saliva.
